WILLIAM P. RICE, OF SHEILBIANA, KENTUCKY.

MINERS LAMP.

To all whom it may concern:

Be it known that I, IVILLIAM P. RICE, a citizen of the United States, residing at Shelbiana, in the county of Pike and State of Kentucky, have invented new and useful Improvements in Miners Lamps, of which the following is a specification.

The invention relates to lamps, and more particularly to the class of miners lamps.

The primary object of the invention is the provision of a lamp in which an air passage is disposed within the wick tube, the passage being extended into the body of the lamp, so that air heated by the flame will enter the interior of the lamp for the melting of the contents thereof, and also eifect an increased illuminating power.

Another object of the invention is the provision of a lamp of this character in which air may be admitted to the interior thereof, so as to increase the fluidity of the fuel confined therein, thus assuring perfect combustion of the fuel and increasing the light therefrom.

A further object of the invention is the provision of a lamp which is simple in construction, thoroughly reliable and efficient in operation, and inexpensive in manufacture.

With these and other objectsin view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

In the drawings: Figure 1 is a side elevation of a lamp constructed in accordance with the invention. Fig. 2 is a vertical longitudinal sectional view thereof. Fig. 3 is a top plan view.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings by numerals, the lamp comprises a conical-shaped body 5, preferably constructed from tin, although it may be made from any other suitable mate rial, and is provided with a wick tube 6, the latter being rearwardly inclined and communicating with the interior of the body, and in which is disposed the ordinary wick 7 which absorbs the oil contained within the body 5 of the lamp for lighting purposes when ignited. The body 5 of the lamp at Specification of Letters Patent.

Serial No. 602,627.

its top may be closed in any suitable manner, preferably by a removable cap 8 which permits the filling of the body 5 with oil when required. Suitably secured to the body 5 exteriorly thereof is a hanger hook which is of the ordinary we1l-known construction, whereby the lamp may be mounted upon a miners cap in the usual manner. Formed on the wick tube 6 is an air tube 10, the same being extended within the body 5 of the lamp and terminates in a circular end 11, the latter being soldered or otherwise secured within the'said body contiguous the bottom thereof, the circular end 11 being suitably perforated so that air admitted through the air tube 10 will be let into the said body 5. The air tube 10 is longitudinally disposed on the wick tube 6 and coextensive therewith, the air tube 10 being secured to the wick tube 6 in any suitable manner. Telescoping within the outer end of the air tube 10 is a wire 12, the same being provided with an outturned free end 13 which is adapted to be thrown into the path of the flame issuing from the wick 7 or away from the same. Thus, it will be seen that when the outturned end 18 of the wire is turned into the path of the flame issuing from the wick 7 the air admitted into the tube 10 will be heated, and when the said outturned end 13 is shifted out of the path of the flame from the wick, the air admitted into the body 5 of the lamp will be cool.

l/Vhat is claimed is:

In a miners lamp, a frusto-conical-shaped body having a wick tube projecting outwardly and upwardly therefrom, a wick disposed within the tube, an air tube coextensive with the wick tube and contiguous thereto, the inner end of the said air tube being extended interiorly of the body and terminating in a circular perforated end resting upon the bottom of the said body, and a wire rotatably mounted in the outer end of the air tube and having an outturned end adapted to be swung into and out of the path of the flame of the wick when ignited.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM P. RICE.
